I'd wager that resilient defectors would not create long-term stable cooperation. They might create stable defection, so in that way adding stability would create stability. But only one of those stable outcomes is actually desirable.

My guess is there's a relationship between the duration to reach stability and how soon after the "fake" players are removed.
